          1. In the chromatogram of the assay, the retention time of the principal peak in the chromatogram obtained with the test solution should correspond to that of the principal peak in the chromatogram obtained with reference solution.

          2. The IR absorption spectrum of the substance to be examined should correspond to that of the reference

          spectrum(No.l 122).
